Background and aim As the number of elderly people visiting dental clinics increases, it is essential to have sufficient information on the correct treatment as well as the appropriate treatment plan for these patients. Therefore, the present study aimed at reviewing the most important restorative considerations for the elderly. Method In this systematic review study, databases such as Pubmed, Embase, Web of Science, Scopus, ProQuest, Google scholar, as well as Iranian databases were searched with the keywords of elderly dentistry and restorative considerations. Inclusion criteria were original articles and reviews related to restorative dentistry considerations for the elderly without a time limit and being written in either English or Persian. In order to combine the results of the research, a thematic content analysis method was applied. Results The total number of documents recovered was 4208, the number of duplicate documents was 2042, and the number of documents reviewed was 17. The most important considerations related to the elderly included giving due attention to medical and social conditions, medication use, type of restorative teeth, level of restoration involved, use of dentures, age and gender, oral cancer screening, tooth decay education and prevention, and oral hygiene. The most important considerations related to restorative methods and materials were applying minimally invasive methods such as ART, more durable restorative materials, and giving due attention to the aesthetic and non-aesthetic needs of the elderly in choosing restorative materials. The most important considerations related to dentists were the differences in applying restorative methods and materials by experienced dentists in comparison younger dentists and the rate of referral of elderly people to dental centers. Conclusion The most important dental considerations of the elderly are using minimally invasive methods and restorative materials with easy maintenance which are washable according to their social, economic, medical, gender, and age conditions. It is also necessary to consider the prevention of tooth decay and provide the required training for families and their caregivers in nursing homes. The elderly people are also required to avoid change their dentists frequently to maintain their oral health. [ABSTRACT FROM AUTHOR]

Introduction: The high success rate of implants has made implant-based prostheses attractive to edentulous patients. Osseointegration lasts 4-6 months, increasing to 6-8 months in cases requiring bone grafts and guided bone regeneration. Many efforts have been made to accelerate osseointegration, including low level laser (LLL) and light emitting diode (LED) photobiomodulation. Materials and methods: Twelve patients underwent bimaxillary immediate implant surgery with particulate bone grafts between the socket wall and the implant, and the transmucosal abutment was attached on implants at the same time. The intervention side was exposed to LED radiation for 20 minutes a day one day preoperatively and 10 consecutive sessions, starting from the day of surgery. A trained operator measured and recorded the implant stability quotient (ISQ) value on both sides immediately after surgery as well as one month and three months postoperatively. Results: The ISQ value was 37.54 on the non-irradiated side immediately after surgery; it decreased to 35.09 one month postoperatively and increased to 46.45 at three months after the operation. The ISQ value was 36.73 on the irradiated side immediately after surgery and it increased to 47.36 and 71.18 at one month and three months postoperatively, respectively. There were significant differences between the ISQ values on the irradiated side at all the three time intervals, but also a significant difference on the non-irradiated side, except for two other two time intervals of immediately and one month after surgery. Although there was no significant difference between the two sides in terms of the ISQ value immediately after surgery, the ISQ value was significantly higher on the irradiated versus non-irradiated side at one month and three months postoperatively. Conclusion: Low level laser radiation resulted in a favorable increase in the ISQ value in three months. Light emitting diode has lso led to a clinically significant increase in the ISQ value after three months because implants with ISQ values >54 could be loaded. [ABSTRACT FROM AUTHOR]

Background: One of the most impressive factors discouraging many people from seeking dental treatment is the fear of experiencing pain during dental procedures. Thus, the use of an effective method for pain control is vital in this regard. Articaine, which has an additional ester and thiophene groups that increase its biosolubility and permeability compared to older anesthetic agents, can be more effective on inducing anesthesia during dental treatment. Given the inconsistent currently available information on this concept, the present study was designed to compare the efficacy of articaine with that of lidocaine on pain control during pulp treatment of deciduous molar. Methods and materials: In this cross-sectional study, 38 patients who needed pulpotomy in both mandibular second molar of primary teeth were randomly divided into two groups, using the Randlist software. In the first meeting, infiltration with articaine 4% (epinephrine 1/100 000) was performed for all patients in group 1 on the left side of the mandible. At the next appointment, inferior alveolar nerve block was done with lidocaine 2% on the right side of the mandible (epinephrine 1/80 000). Notably, for all patients in the second group, the first injection was performed on the right second primary molar with articaine 4% (epinephrine 1/100 000), and inferior alveolar nerve block was also done with lidocaine 2% on the left side of the mandible (epinephrine 1/80 000). Results: Of the 38 patients included in the current study, 10 (26.3%) subjects in the lidocaine group and nine (23.6%) in the articaine group complained of pain during their dental treatment procedures, but this difference was not statistically significant. Conclusion: According to the findings of this study, buccal infiltration of 4% articaine had a comparable anesthetic outcome to that of 2% lidocaine for inferior alveolar nerve block in pulp treatment of the second primary mandibular molars.

Background: This in vitro study was conducted to compare the effect of universal bonding application strategy (i.e., self-etch and etch-and-rinse) on marginal adaptation of bulk-fill and conventional composite resins in Class II restorations. Materials and Methods: In this in vitro study sixty sound premolars extracted for orthodontic reasons were selected. The samples were allocated to four groups based on the universal bonding application strategy (self-etch and etch and rinse) and type of composite (bulk-fill and conventional). In each group, boxes were prepared with a depth of 4 mm on the mesial surfaces. Finally, the marginal adaptation of the samples was evaluated under a stereomicroscope. Two-way ANOVA was used to compare the marginal adaptation data in the study. Statistical significance was set at P < 0.05. Results: Considering the type of universal bonding application strategy, there was a statistically significant difference in marginal adaptation. Etch-and-rinse strategy showed better marginal adaptation compared to self-etch strategy (P < 0.001). However, there was no statistically significant difference in marginal adaptation between the two composite resins (P = 0.829). Furthermore, the interaction between the two factors (type of universal bonding application strategy and type of composite resin) was not statistically significant (P = 0.629). Conclusion: Etch-and-rinse bonding application strategy in both the bulk-fill and conventional composite resins exhibited better marginal adaptation compared to self-etch bonding application strategy. However, the difference of marginal adaptation between the two types of composite resins (bulk and conventional) was not significant. [ABSTRACT FROM AUTHOR]
